The invention discloses a vehicle, a hanger bracket and a method for measuring and calculating a mounting inclined angle of a tray of the hanger bracket. The method for measuring and calculating the mounting inclined angle of the tray of the hanger bracket comprises the following steps: acquiring a helix equation of a contact line under a X minute minute Y minute minute Z minute minute coordinate system through the transformation of coordinates according to the known helix equation of the contact line at a contact part between the tray and a lower supporting ring of a spring; solving the equation, acquiring the mounting inclined angle of the tray; placing the tray after being inclined for the mounting inclined angle on a mechanical model of the vehicle; calculating a lateral force of a shock absorber; acquiring the stresses of the shock absorber at different mounting inclined angles by changing the mounting inclined angle, thereby acquiring the optimal mounting inclined angle. When the tray is inclined for the optimal mounting inclined angle, the lateral force of the shock absorber counteracts with the lateral force of a vehicle body. According to the method for measuring and calculating the mounting inclined angle of the tray of the hanger bracket provided by the invention, the optimal mounting inclined angle can be measured and calculated. After the tray is mounted at the optimal mounting inclined angle, the comfort level of the vehicle is increased.
